3.6 RFC35 Fluxgate Compass installation
The heading sensor is the most important part of the AP300X system
and great care should be taken when deciding the mounting location.
As the sensor heading is displayed on the AP300X Control Unit, the
heading sensor can be mounted at any location where there is a
minimum of magnetic interference.
Note ! An autopilot heading sensor should not be installed on the fly bridge or in
the mast.
The RFC35 compass can be deck mounted or on the bulkhead,
athwartship or alongship. The heading offset feature in the AP300X
will compensate for the mechanical offsets that may be a result of the
selected location and orientation of the RFC35.
If the RFC35 is deck mounted or bulkhead mounted athwartship with
the cable gland pointing aft, little if any offset correction is required.
With the cable gland pointing forward a 180° correction is required.
When mounting RFC35 on a bulkhead alongship, a +90° or -90°
correction is needed dependent on whether it is a port or starboard
bulkhead.
Select a location that provides a solid mounting place free from
vibration, and as close to the vessel's center of roll and pitch as
possible, i.e. close to the water line. It should be as far as possible from
disturbing magnetic influences such as the engines (min. 2 meters),
engine ignition cables, other large metal objects and particularly the
drive unit.
Use the supplied mounting kit and drill the holes through the center of
the slots in the sensor or the mounting brackets.
The compass face- plate on the RFC35 is the TOP. Never mount it
upside down! Level the sensor as close to horizontal as possible.
